摘要
以纸浆材示范林和种子园子代测定林为基础材料,兼顾扦插生根率、造林成活率、采穗母株的生长量及材性性状(木材密度)等综合指标,经过初选和复选,最终筛选出纸浆材优良无性系39个 这批无性系6年生林分材积、胸径、树高生长量均超过实生林分的226%、75%、42%,生根率超过初选无性系28%,木材比重的选择增益平均达到8 7%
Thirty-nine Pinus massoninana 'clones for pulp use were selected from forests of fine provenance , progeny test trees of seed orchard by two steps of selection ,based on the growth , wood property of the ortets and rooting abilities of cuttage.The average height , DBH and volume growth of these clones at six years old were 42 percent and 75 percent and 226 percent respectively higher than those from seedlings . and average section gain of wood density got to 8.7 percent. Some first-class families selected from these testing breeds can be chosen establish Pinus massoniana cutting orchard.
